1. Kurima mbesa dzakasimba mumupunga: Nguva yakanakisisa yemupunga ishizha rimwe chete, nguva yemoyo mumwe, inova mazuva mashanu kusvika manomwe mushure mekudyara. Chiyero chakakodzera che15% paclobutrazol wettable powder i3 kg pahekita ne1500 kg yemvura yakawedzerwa (kureva magiramu 200 epaclobutrazol pahekita ne100 kg yemvura yakawedzerwa). Mvura iri mumunda wembesa yaoma, uye mbesa dzinopfapfaidzwa zvakaenzana. Kuwanda kwe15% paclobutrazol kwakapetwa ka500 kupfuura mvura (300ppm). Mushure mekurapwa, mwero wekureba kwembesa unodzikira, zvichiita kuti pave nemigumisiro yekudzora kukura, kukurudzira kurima, kudzivirira kutadza kwembesa, uye kusimbisa mbesa.
2. Kurima mbesa dzakasimba muchikamu chemashizha matatu embesa dzerape, shandisa 600-1200g ye15% paclobutrazol wettable powder pahekita, uye wedzera 900kg yemvura (100-200Chemicalbookppm) kupfapfaidza madzinde nemashizha embesa dzerape, kukurudzira kugadzirwa kwechlorophyll, kuvandudza mwero we photosynthesis, kuderedza chirwere che sclerotinia, kuwedzera kusimba kwemuti, kuwedzera mapods uye goho.
3. Kuti soya isakure nekukurumidza kupfuura pakutanga kwekutumbuka, 600-1200 magiramu e15% paclobutrazol wettable powder pahekita, 900 kg yemvura (100-200 ppm), uye pfapfaidza mvura iyi padzinde nemashizha embeu yesoya kuti udzore kureba, kuwedzera mapods uye goho.
4. Kudzora kukura kwegorosi uye kudiridza mbeu nepaclobutrazol zvine hurefu hwakakodzera, zvinopa mhodzi dzakasimba, zvinopa muriwo wakaderera, uye zvinopa goho rakawanda pagorosi. Sanganisa magiramu makumi maviri e15% paclobutrazol wettable powder nemakirogiramu makumi mashanu embeu dzegorosi (kureva 60ppm), nekuderedza hurefu hwechirimwa ne5% muChemicalbook. Yakakodzera kudyara gorosi nekukurumidza nehupamhi hwemasendimita maviri kusvika matatu, uye inofanira kushandiswa kana mhando yembeu, kugadzirira ivhu, uye hunyoro zviri zvakanaka. Parizvino, kudyara nemuchina kunoshandiswa zvakanyanya mukugadzira, uye kunogona kukanganisa mwero wekumera kana kudzika kwekudyara kwakaoma kudzora, saka hazvina kukodzera kuishandisa.
